Love pulls us out of the muck of relativism where we judge how to treat each other by what we at that moment prefer. Love restores us to the goal of preferring one another better than himself.
Through love, always unselfish and devoted, we have a means to judge our thoughts and actions. Love always considers the other person's life, needs and goals in life.
Through the view of love, we will see that many of our relationships are self-oriented rather than other-oriented. We will learn to reject those things which in fact serve ourselves and instead get bold in doing what is right and good even at our own personal costs.
